ALBERT BIERSTADT, OF NEW YORK, N. Y.

RAILWAY-CAR.

SPECIFICATION forming part of Letters Patent No. 566,127, dated August18, 1896.

Application filed May 13, 1896. Serial No. 591,394. (No model.)

To all whom it may concern:

Be it known that I, ALBERT BIERSTADT, a citizen of the United States,residing at New York, in the county and State of New York, have inventedcertain new and useful Improvements in Railway-Oars or other LikeVehicles, of which the following is a specification, reference being hadtherein to the accompanying drawings.

The invention relates to a railway-car the sides and roof of which arecapable of being extended toform an enlarged car suitable for purposesof lecturing, camping out, exhibiting pictures or other articles, andalso suitable for a chapel or church, theater, &c.

The invention consists of improvements upon the apparatus shown anddescribed in my application for patents, filed October 15, 1895, SerialNos. 565,806 and 565,807; and it also .consists of the novel features ofconstruction hereinafter set forth and described, and more particularlypointed out in the claims hereto appended. I

Referring to the drawings, Figure 1 is a transverse vertical section ofthe car with the roof raised and the sides extended or unfolded. Fig. 2is a transverse vertical section of the car with the roof and sidesclosed. Fig. 3 is a bottom view of the car-floor. to 7, inclusive, aredetail views showing mechanism for moving the various parts. Fig. 8 is asection taken on the line 8 8 of Fig. 7.

Like numerals refer to like parts throughout the several views.

In the accompanying drawings the numeral 1 denotes the floor of the car,to which is attached the posts or standards 7, which form a support forthe roof when not raised or extended. These posts are provided with atelescoping portion 7, which latter, in connection with the ropes andpulleys hereinafter described, support the roof when raised or extended.

9 denotes a portion of the side of the car hinged to the floor, which,when extended or unfolded, forms a wing or extension floor.

denotes a portion of the side of the car hinged to the posts 7, whichwhen extended forms the end of the wing or extension, as shown in dottedlines, partly broken away, in Fig. 4.

Figs. 4

17 denotes a portion of the side wall hinged to the strip 18, of wood ormetal, which strip in turn is attached to the portion 9. 16 denotesanother strip similar to'18, attached to the part 17. These strips ofwood or metal prevent the parts 9 and 17 from touching when folded, andtherebyprevent injury to the pictures or other articles which may beattached to the part 17.

2O denotes a portion of the side of the car hinged to the extensibleroof 21, which portion when raised forms the wing or extension roof.This part 20 when closed forms the outside portion of the sides of thecar, and when closed may be secured by any suitable means.

The extensible roof and the wing-roof are raised simultaneously by meansof the mechanism now to be described.

22 and 23 denote beveled gear-wheels, and 24 a screw connection betweenthe wheel 23 and the cross-head 25, which latter slides in the guides26.

27 27 denote flexible connections between the said cross-head and thecross-head 30, and running over pulleys 28 29, and 31 31 denote ropes orchains connecting said cross-head to the base of the posts 7 t andrunning over intermediate pulleys 32 32.

33denotes a rope secured to the floor of the car passing over pulleys 3434 34 and connected to the roof 20. 35 denotes beams sliding in the topof the extensible roof.

The part 9 when extended is supported in part by a flange extending atright angles to the lower part of the portion 15, and it may also besupported by any suitable means additionally, such as posts placedthereunder.

The parts 9 are lowered and the parts 17 raised by the mechanism now tobe described.

36 and 37 denote beveled gear-wheels, and 38 a screw connection betweenthe wheel 37 and the cross-head 39, passing between the rods 40. 41denotes another cross-head, and 42 a pulley attached thereto. Thesecrossheads and 41 slide in the guides 43 43.

44 denotes a rope or chain attached to the floor of the car 1 andpassing around the pulley 42, thence around the pulleys 45 45 and 46 andadapted to pass around the pulley 47, and also adapted to be connectedwith either the outer end of the extension-floor 9 or the upper portionof the sides 17 according as to whether it is desired to raise the part9 or lower the part 17 as the case may be, as shown in dotted lines,Fig. 1.

48 is a key, and 49 49 cranks by which the gear-wheels are operated.

The operation of the mechanism described above is as follows: Thegear-wheels 22 and 23 are operated by turning the key 48, which causesthe cross-head 25 to be drawn toward the center of the car by means ofthe screw 24. This causes the ropes 27 which run over the pulleys 28 29to pull the cross-head 30 and the ropes 31 31, running over pulleys 3232, down, thereby raising the extension-posts 7 n and thus raising theextensible roof. By this operation the braces or beams 35 are graduallyforced outwardly owing to the tension on the rope 33, which at the sametime gradually raises the roof 20. When the roof 20 is lowered, thebeams 35 are gradually forced inwardly by the weight of said roof. Thegear- Wheels 36 37 are operated by turning the crank 49, which causesthe cross-heads 39 and 41 to be drawn toward the center of the car bymeans of the screw 38. This causes the rope 44 by means of intermediatepulleys 45 45 and 46 to lower or raise the portion 9 when it is attachedthereto. WVhemhowever, the said rope 44 is connected to the part 17 andthe screw 38 is operated, the part 17 is raised or lowered by means ofthis rope and intermediate pulleys 45 45, 46, and 47.

The operation of closing the car is simply the reverse of that ofopening it.

The car may be made of any suitable size and preferably is made in threesections, so that the parts may be readily moved into position, and ismade of material ordinarily used in the construction of Pullman cars.

What I claim as my invention, and desire to protect by Letters Patent,is

1. In a railway-car or other like vehicle, the combination of anextensible roof and means for raising or lowering the same, consistingsubstantially of a gear-wheel, screw, a crosshead, pulleys, and aflexible connection between said cross-head and the said roof,substantially as described.

2. In a railway-car or other like vehicle, the combination of the posts7, extension-posts 7 extensible roof and means for raising or loweringthe same, consisting substantially of a gear-wheel, screw, a cross-head,pulleys, and a flexible connection between said crosshead and the posts7, substantially as described.

3. In a railway-car or other like vehicle, the

combination of an extensible roof, means forraising or lowering thesame, a swinging portion 20, and a flexible connection between thecar-body and said portion 20, running over a suitable pulley, wherebywhen the extensible roof is raised or lowered, the said portion 20 issimultaneously raised or lowered into position, substantially asdescribed.

4. In a railway-car or other like vehicle, the combination of anextensible roof, means for raising or lowering the same, a swingingportion 20, a flexible connection between the floor of the car and thesaid portion 20 passing over pulleys on an automatically-sliding beam35, substantially as described.

5. In a railway-car or other like vehicle, the combination of a swingingportion 9, and means for lowering or raising the same into position,consisting substantially of a gearwhcel, screw, cross-head, and flexibleconnections between said cross-head and the outer end of said portion 9,and passing over suit able pulleys, substantially as described.

6. In a railway-car or otherlike vehicle, the combination of theswinging portion 9, the portion 17, and means for raising or loweringsaid portion17 into position, consisting substantially of a gear-wheel,screw, cross-head, and flexible connections between said crosshead andthe upper part of said portion 17, substantially as described.

In witness whereof I have hereto affixed m y signature, this 24th day ofApril, 1896, in the presence of two witnesses.

ALBERT BIERSTADT.
